Description
Technical field
The present invention relates to a kind of processing technology of glass lamp housing, the preparation side of particularly a kind of low ultraviolet radioactive light fixture glass bulb
Method.
Background technology
Optical radiation is the radiation wave band the closest with human contact.In the wave band of light radiation, the radiation of ultraviolet is right
The injury of human body is than more prominent.The species of light fixture is varied in the market, and either the unique ornament lamp of pattern is still each
The illuminating lamp of formula various kinds is all much to be lighted using glass bulb.Ultraviolet all can be produced, ultraviolet presses its ripple when these light shine
Long difference, generally can be divided into three kinds：UV-A (315～400nm), UV-B (280～315nm), UV-C (
<280nm) etc..Wherein UV-B is maximum to the harm of environment and the mankind, and human body absorbs UV-B for a long time and skin can be led to old
Change, pigmentation or even skin carcinoma, and for environment, UV-B can lead to biomass to reduce, earth's surface air pollution aggravation.
With the development further of lighting engineering, after especially LED lighting source occurs, the light radiation of light fixture, especially ultraviolet radioactive
Drastically influence ecological environment and the health of the mankind.Developing low ultraviolet radioactive light fixture glass bulb is that domestic light trade is badly in need of solution
Technical barrier certainly.Traditional general employing of glass with ultraviolet radiation preventing function adds CeO in simple glass2As
UV absorbent.CeO2It is excellent and using more ripe ultraviolet shielded material, but it has a major defect, that is, relatively
High oxidisability, works as CeO2When addition is less than 0.06%, ultraviolet permeability height is it is impossible to meet international industry standard, and CeO2
Addition be more than 0.1% when, occur that glass bulb color and luster is partially yellow again, affect light transmittance.For solving this problem it is contemplated that gold
Red stone-type nano-TiO2Inorganic particle has stronger absorption and reflectance to ultraviolet, and this project is prepared rutile-type first and received
Rice TiO2- CeO2Compound ultraviolet absorber.
Content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of preparation method of low ultraviolet radioactive light fixture glass bulb.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of preparation method of low ultraviolet radioactive light fixture glass bulb it is characterised in that：Comprise the following steps：
One, prepare raw material, be combined ultraviolet absorber two including ordinary glass material and rutile type nano titanic oxide-cerium oxide
Plant raw material,
Rutile type nano titanic oxide-cerium oxide is combined uv absorption agent content：0.12%-0.24%, ordinary glass material
Content and rutile type nano titanic oxide-cerium oxide to be combined ultraviolet absorber percentage composition summation be 100%, wherein gold
Red stone-type nano titanium oxide and cerium oxide ratio are 5:3,
Two, using glass disintegrating machine, ordinary glass material is smashed, then using sifting machine filter off non-compliant granule and
Impurity,
Three, above two raw material is weighed respectively, and forms compound according to the percentage composition mix homogeneously of step one,
Four, the compound in step 3 is sent into smelting furnace fusing, and clarifies elimination visible bubble in bubble, homogenizing eliminate chemistry uneven and
Heat is uneven, and temperature of smelting furnace is 1500-1700 degree Celsius,
Five, it is then injected into mould cooling shaping chunk glass,
Six, by annealed for the chunk glass of molding elimination internal stress after again retrofit be finished product.
The component of described ordinary glass material and percentage composition are：
Silicon dioxide 74-78%
Diboron trioxide 14-17%
Sodium oxide 5.0-5.5%
Potassium oxide 0.3-1.0%
Aluminium sesquioxide 2.8-3.8%
Phosphorus pentoxide 0.04-0.05%
Magnesium oxide 0.04-0.05%
Calcium oxide 0.04-0.05%
Barium monoxide 0.04-0.05
Zinc oxide 0.04-0.05%
Lead oxide 0.04-0.05%
Iron sesquioxide 0.03-0.04%
The percentage composition summation of said components is 100%.
The preparation process that described rutile type nano titanic oxide-cerium oxide is combined ultraviolet absorber comprises following process：
Metatitanic acid acidolysis hydrolysis washing calcining inorganic coating organic process adds cerium oxide
Superfine grinding processes and obtains the compound ultraviolet absorber of last rutile type nano titanic oxide-cerium oxide.
A kind of preparation method of low ultraviolet radioactive light fixture glass bulb according to claim 1 it is characterised in that：Described gold
It is 0.21% that red stone-type nano titanium oxide-cerium oxide is combined uv absorption agent content.
The invention has the beneficial effects as follows：This method prepares rutile type nano TiO first2（Titanium dioxide）- CeO2（Oxidation
Cerium）Compound ultraviolet absorber, then adds rutile type nano TiO in common glass bulb raw material2- CeO2Compound uv absorption
Agent, blended, high temperature melting, clarification, homogenizing, cooling, shaping, develop ultraviolet（UV）It is (international same that transmitance is less than 50%
Industry standard) and the still excellent light fixture glass bulb of other performances.
Nano-TiO2Inorganic particle has stronger absorption and reflectance to ultraviolet.TiO2There are Detitanium-ore-type, rutile-type
With 3 kinds of brookite type, the nano-TiO of rutile-type2Energy gap is 3.0 eV, works as nano-TiO2Inhale as the ultraviolet in light fixture
When receiving agent, rutile TiO2Absorption ultraviolet performance highest, thus preferred rutile TiO2, rutile type nano TiO2
Feature as follows:One is that specific surface area is big;Two for light absorption good and absorb UV resistance strong;Three is that surface activity is big.Grain
The gold redrock nano TiO of footpath about 25 nm2The absorption reflecting properties of UV-A and UV-B are peaked, is equal grain
Footpath Nano-meter SiO_22With 3～6 times of nano-ZnO, and nano-TiO2I.e. nontoxic, tasteless and nonirritant, security performance is high, has again
There are very high heat stability, chemical stability.
CeO before2It is used alone more, CeO2There is more powerful ultraviolet absorption ability, CeO2Absorb ultraviolet after with
The form of light releases energy, CeO2Though absorb ultraviolet its visible ray is no absorbed substantially, to normal lamp lighting
Have no effect.And there is more good chemical stability, it is a kind of excellent and the more ripe UV absorbing material of application.But
There is all defects, such as higher oxidisability is subject matter.CeO2Because there is strong oxidizing property therefore being commonly used to make glass
Decolorising agent.CeO2Generate Ce at high temperature2O3Discharge oxygen, colour the Fe generating after stronger FeO is reacted with oxygen2O3Coloring is relatively
Weak, generate Ce simultaneously2O3.Scientist finds, as CeO in glass bulb2Addition be less than 0.06% when, due to CeO2Purple
Outer absorbability is directly proportional to its consumption, and the glass bulb sample ultraviolet permeability of preparation is high, does not reach international industry standard
Requirement.For reaching the standard to glass bulb ultraviolet permeability for the international industry standard, researchers increase CeO in glass bulb2
Addition, but work as CeO2Addition be more than 0.1% when, another problem occurs again：The partially yellow problem of glass bulb color and luster,
Impact is produced on the visible light transmittance rate of glass bulb.
Because above-mentioned reason, CeO2Can not add, but the effect that amount not absorbs ultraviolet not reach again, then select with
Absorb the also very outstanding rutile type nano TiO of ultraviolet performance2It is combined into ultraviolet absorber together and can reach extraordinary effect
Really, by with CeO2Modification make rutile type nano TiO2Uv absorption property is obviously improved, is combined
The uv absorption property of ultraviolet absorber is better than the single powder body of any of which.
